We can build her back...Stronger, Better, Faster.

 

This floor picture isn't the worst news I got today.  The frame rail is bent and cracked down by the pedal box.  Every problem I find is just an opportunity to make it stronger. I think she was moderately "tapped" in the front driver's corner.

My guess is that the floor rust by the pedal box is the result of a long-term leaking clutch master cylinder.  It'll eventually fill the pedal box--it'll hold over a pint--(rusting it out too) if you keep adding fluid without checking where it's going.  

 

And the frame rail rust probably began from a leaking brake master cylinder.  It'll drip and run down inside that driver's side frame rail, eventually rusting it from the inside out.  I'll bet the crunch is from a jack being used on the already weakened frame rail.

 

I learned both of the above lessons when they happened to my '69.  Both spots were repaired many years ago--replacement pedal bucket and replacement last two feet of the frame rail.

Is it possible to drop the subframe about an inch or two to make repairs easier?  I’m sure the driver’s frame rail needs completely replaced but I would like to strongly “patch” this and do the whole frame rail when I drop the subframe/engine/trans.  My metal skills are enough to do a temporary sound patch job, and handle the full replacement later.

If it was me I think I would do the repair once and do it right!

 

I have a feeling you're going to find more rust and other things that need attention.

 

I would suggest dropping the whole engine transmission and subframe as one unit. It can be done with a motorcycle/ATV jack.

Some more work to clean up things for welding (that tar sh!+ sucks), then I can start the cardboard pattern fun.  I'm gonna go further left to find good metal.  I'm pretty sure the fuel return line runs down that area so, I will be sure to protect it.  I also realized that 16 gauge steel is likely too thick.  I would be ok with +0.005" over gauge, but not 0.015" over.  I am going to reinforce the ring around the pedal box mount on the inside.

Looks good so far, if that’s the extent of  the damage there you are lucky.

The frame rail will be more of a pain, you could probably box in that area IF it’s not rusty on the inside,  if so it may not be solid enough to weld.
You can lower the subframe/engine  a bit but still have to separate the  steering coupler, trans mount, coolant hoses , clutch  MC  to slave  cyl as well as struts top or bottom.  
Not all that much more( exhaust at down pipe, driveshaft coupler bolts, a few wires) and you could lower the whole shebang onto a furniture dolly and roll it out of your way.

No one sees down there and it looks stout. Nice work.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
